Private Secondary Service Paths (PSSPs) between compatible or non-compatible communication terminals (110, 120) are established using terrestrial stations (130) within a satellite communication system (100). Each PSSP provides to its users the ability to establish communication paths between compatible or non-compatible terminals. A PSSP is established using terrestrial stations (130) which establish and maintain terrestrial-based links (115, 125) and satellite communication links (135). Terrestrial stations also perform frequency translating and data reformatting to allow non-compatible terminals to communicate with each other. All data can be sent between terminals over satellites (140), or user data can be sent via terrestrial connections (150) while overhead data is sent via satellites (140).
